Memory Power Macintosh - 1 9
Power Macintosh
8600 Series
The Power Macintosh 8600
Series logic boards have eight
DRAM DIMM slots, each with
a 64-bit data bus. You can
increase the computer’s
DRAM to a total of 512 MB
using 5-volt, 64-bit-wide,
168-pin fast-paged mode or
EDO DIMMs.

VRAM DIMM slots
VRAM Note: This computer uses VRAM
DIMMs (112-pin, 70 ns or faster) instead
of VRAM SIMMs. The VRAM SIMMs used in
earlier Power Macintosh models are not
compatible. There are 4 VRAM slots. 1 MB
DIMMs are installed in pairs, making VRAM
expandable to 4MB.
Memory Information
DRAM Speed 70 ns
DIMM Type +5V 168-pin
Soldered DRAM None
Number of DIMM Slots 8
Supported Sizes in MB 4, 8, 16, 32, 64
Maximum DRAM 512 MB
Virtual Memory 1 GB
Soldered VRAM None (See Note)
Number of VRAM Slots 4 (2 MB
installed)
Note: DRAM DIMMs can be installed
individually; however, to provide maximum
performance, install the DIMMs in matching
pairs and in paired slots (A4 and B4 first,
then A3 and B3, etc.).
Note: The Single In-Line Memory Modules
(SIMMs) used in previous Macintosh models
are NOT compatible with the Power
Macintosh 8600. This computer supports
+5V DIMMs only.
Note: The Power Macintosh 8600 does not
have any main memory soldered to the logic
board. At least one DRAM DIMM must be
installed for the computer to operate.
DRAM Configurations
